Re: Side effect of the countback system
30 is based on statistical theory. A certain number of game results (n) will give you a x% probablility that your grade lies in the interval G-y to G+y. Elo has a table of y versus n (I think).

Re: Side effect of the countback system
I am not saying it will create a problem (I am not sure if it does or not) but if your performance varies throughout the year (e.g. because of the different type of events that take place at different times of the year) then the grade calculated under the countback system will certainly be different...

Side effect of the countback system
Consider a player who plays 40 games a year. Because of the count-back method the 10 games he plays immediately before the end of the cut off period will be counted twice in calculating his grade (i.e. in January and July) whereas the other 10 games will be used just once. Is this what we want under...

Re: Elaine Saunders/Pritchard (1926-2012)
John Beasley was responsible for completing the 2nd of "the Encyclopedia of Chess Variants" (2007). The first edition was produced by David P in 1994. I remember playing Elaine a few times in Border League Guildford v Godalming matches (I have found a game score for 5th Jan 1998, French defence exch...

Re: Draft Junior Selection Policy for 2012
Grades always come out at about the time of the British Championships so it is not that unusual for some events there to make use of "old" grades.

Re: Adjournment Tales...
Isn't there a variation of the adjournment story where the sealer/ resigner doesn't turn up and the opponent opens the envelope to read some insult. (I don't recall the name of the sealer.)

Re: Trent and Gordon Commentary at the Classic
The guys who sit in front of the cameras are being paid to do so, of course. (And a random GM who came and sat in front of the cameras wouldn't be.)

A pedantic point: pants are not the same as trousers (except in the USA).

Re: An Open Letter to CJ De Mooi
>>>He [Ray Keene] also offered to shake hands with Lara but without offering an apology.<<<
Just to give the full picture: he also offered to issue a statement saying that he does not regard Lara as homophobic.

Re: An Open Letter to CJ De Mooi
Ernie, as you don't lie then we will have to put it down to ignorance as I have known CJ for many years as an active player and a sponsor of chess.

Re: An Open Letter to CJ De Mooi
Ernie, apologies if I incorrectly attributed the self-publicist jibe to you incorrectly. "Transient" is bad enough in my book.

Re: An Open Letter to CJ De Mooi
Ernie, you described as a transient whose only reason for attaching himself to the ECF is self-publicity. I know for a fact that this is a lie.
